I'm for an app that helps me normalize the volume of audio files that have different volume. When making compilation CD's with music from different albums, the audio files often have very different volume. I don't like itunes built in volume fix because it's sets the volume on all tracks to very low, so you have to krank up the volume on your stereo.

Roxio Jam has some nice normalization features as I recall. Haven't used it in a while. Other than that mAC3Dec can do it, it supports QT input and output, as well as LAME mp3 encoding.

Actually, iTunes' volume correction *is* just normalization, AFAIK.

Realize that "loudness" is actually a *lot* more than just whether or not an audio file peaks at 0dB - almost all commercially produced recordings do.

Compression, mix, mastering, etc., all have lots more to do with the perceived volume of a track, and there's not much you can do except compress everything to hell - which is what they do on the radio, and why radio is such atrocious audio quality these days (almost no stations any longer even fulfill the basic "hi-fi" norms for minimal audio fidelity once set in the the 1960s).

I get your point. I know I cant achieve a perfectly mastered album with the same loudness on all tracks. But I still think that if I could get all tracks to peak at 0dB the a compilation album. The thing with iTunes is it sets the volume of all of my mp3's to a specific volume. And if I rip a new album that is well mastered, the volume dix sets the volume at lika half the normal volume. I want an app that normalizes the volume of the tracks I want to burn on a CD.
